Description

A device for applying wrapper to cigar tobacco blanks Technical Field

[0001] This invention belongs to the technical field of tobacco cigarette forming equipment, and more specifically, relates to a device for applying wrapper to cigar blanks. Background Technology

[0002] According to GB / T 15269, Part 1: Classification and Sampling Technical Requirements for Cigars, cigars are classified according to their weight: large cigars (m≥6.0g), medium cigars (3.0≤m<6.0g), small cigars (1.2≤m<3.0g), and miniature cigars (m<1.2g). Generally, miniature and small cigars are machine-made, while medium and large cigars are hand-rolled. Regardless of the type, a cigar consists of a filler, a binder (if applicable), and a wrapper. The binder (if applicable) wraps the filler to form the cigar embryo, which is then wrapped with the wrapper and rolled to form the cigar.

[0003] Traditionally, mini and small cigars are produced by machine, which is highly efficient. Medium and large cigars are produced by hand-rolling, which is less efficient. The process of hand-wrapping the cigars is also affected by human factors, such as differences in operating skills and fatigue levels, which may lead to differences in the wrapping effect and quality between different operators.

[0004] In summary, the existing cigarette production process suffers from low efficiency in the wrapper application process for cigars, and the processing quality is affected by the skill level of the workers. Summary of the Invention

[0005] In view of this, the present invention proposes an apparatus for wrapping cigar blanks, which can solve the problems of low process efficiency and the influence of worker skill level on processing quality in wrapping cigar blanks.

[0006] This invention is implemented as follows:

[0007] This invention provides a device for applying wrapper to a cigar, comprising a support, a camshaft, and a limiting shaft; the support includes a connecting plate for mounting on a workbench, with a left support plate and a right support plate parallel to each other at both ends of the connecting plate; the camshaft and the limiting shaft are both mounted between the left and right support plates and are parallel to each other, the camshaft is rotatably connected to the left and right support plates, and the limiting shaft is fixedly connected to the left and right support plates; one end of the camshaft is provided with a first motor for driving the camshaft to rotate; In the middle, the top of the left support plate is provided with a needle picking mechanism for picking off the eggplant wrapper and a rolling roller rotation mechanism for rotating the eggplant embryo; the cam shaft is equipped with a first cam, a second cam, a third cam and a fourth cam that are parallel to each other from left to right; the first cam cooperates with the rolling roller opening and closing mechanism to roll the outer wrapper of the eggplant embryo; the second cam and the third cam both cooperate with the wrapper spreading mechanism to achieve wrinkle prevention and flattening of the wrapper; the fourth cam cooperates with the trimming mechanism to complete the finishing action after the eggplant embryo is wrapped with the wrapper.

[0008] The technical effects of the device for wrapping cigar blanks provided by this invention are as follows: By setting a camshaft, a first motor drives the camshaft to rotate, simultaneously driving four cams to rotate, thereby controlling the opening and closing of the winding roller opening and closing mechanism and controlling the operation of the paper winding roller mechanism. The two pairs of rotating rollers on both sides provide power for the rotation of the cigar blank during the wrapping process, thereby causing the upper rotating roller to rub and rotate the cigar blank, realizing the wrapping operation of the cigar blank; and combined with the wrapper unfolding mechanism, under the drive of the second and third cams, the second and third connecting rod assemblies work together to realize the forward and backward movement of the scraper. The lifting mechanism can flatten the wrapper before rolling, effectively preventing quality problems caused by wrinkles when the wrapper is rolled onto the cigar blank, thus improving the quality of wrapper application. The trimming mechanism, driven by the fourth cam, allows for the trimming of medium and large cigars, resulting in a more aesthetically pleasing finish and further improving product quality. This cigar wrapper application device features a compact structure and stable, efficient operation of all components, automating the wrapper application process and significantly improving cigar production efficiency and quality.

[0009] Based on the above technical solution, the device for applying wrapper to cigar preforms according to the present invention can be further improved as follows:

[0010] The rolling roller rotation mechanism includes a second motor mounted on the outer side of the left support plate on the left side. A large gear is coaxially mounted on the output shaft of the second motor. Two small gears symmetrically connected above the large gear are meshed. The rotating shafts of the two small gears pass through the left and right support plates and are rotatably connected to them. An eggplant support is sleeved in the middle of the rotating shaft. A support plate is provided on the top of the right support plate. The eggplant is mounted on the eggplant support and the support plate. A gear box is provided at one end of the rotating shaft near the inner side of the left support plate. Two rotating rollers that can rotate with the gear box are provided on the gear box above the rotating shaft. The rotating rollers are used to drive the eggplant to rotate when closed. A linkage shaft is also fixedly installed at the bottom right side of the gear box. A positioning plate is sleeved on one end of the linkage shaft and the rotating rollers near the right side. The positioning plate is used to limit the relative position between the linkage shaft and the rotating rollers.

[0011] The large gear in the rolling roller rotating mechanism is fixedly connected to the output shaft of the second motor, and the large gear is also located on the outside of the left support plate; two small gears are arranged above the large gear and also on the outside of the left support plate. The rotating shafts on the two small gears are arranged parallel to each other on the same horizontal plane, and the eggplant support sleeved on the rotating shaft is rotatably connected to the rotating shaft. The eggplant placement groove on the eggplant support always faces upward and is kept horizontal with the eggplant placement groove opened on the support plate; the gear box is located on the right side of the left support plate, wherein the rotating shaft and the linkage shaft are located at the bottom of the gear box and the plane containing their axes is parallel to the bottom surface of the gear box; the two rotating rollers are arranged on one side of the gear box and the plane containing their axes is parallel to the side of the gear box.

[0012] Furthermore, the winding roller opening and closing mechanism includes a first linkage assembly, which includes a first roller, a first connecting rod, a second connecting rod, two third connecting rods, and a pin. The first roller is disposed on the front side of the first cam and is fixedly connected to the bottom end of the first connecting rod. The top end of the first connecting rod is fixedly connected to the bottom end of the second connecting rod, and there is an angle between them. The top end of the first connecting rod is hinged to the bottom ends of the two third connecting rods through the pin. The two third connecting rods are symmetrically arranged, and the top ends of the two third connecting rods are respectively sleeved on the linkage shaft and rotatably connected to the linkage shaft. An arc-shaped surface is provided at the connection between the first connecting rod and the second connecting rod, and the limiting shaft is slidably connected to the arc-shaped surface.

[0013] The first roller in the winding roller opening and closing mechanism is located at the lower front side of the first cam, and the arc-shaped surface at the connection between connecting rod one and connecting rod two is located in the slot on the limiting shaft. The arc-shaped surface can roll in the slot, and the limiting shaft is used to limit the swing angle of connecting rod one and connecting rod two. With the above arrangement, connecting rod one and connecting rod two are fixed as a whole. When the first cam pushes the first roller, the connection between connecting rod one and connecting rod two on the first connecting rod assembly cannot undergo relative displacement. It can only swing around the position of the arc-shaped surface as the center, thereby pulling down the pin and closing the winding roller opening and closing mechanism. It has the characteristics of compact structure, smooth linkage, and easy maintenance.

[0014] Furthermore, the eggplant peel spreading mechanism includes a scraper plate, which is disposed above the front side of the rotating roller. A second linkage assembly for controlling its lifting and lowering is fixedly connected to the front side of the scraper plate. The second linkage assembly includes a second roller, a fourth linkage, a fifth linkage, and a sixth linkage. The second roller is disposed above the second cam and is fixedly connected to one end of the fourth linkage. The other end of the fourth linkage is hinged to the bottom end of the fifth linkage. The top end of the fifth linkage is fixedly connected to the bottom end of the sixth linkage. The top end of the sixth linkage is fixedly connected to a connecting shaft disposed on the front side of the scraper plate. The middle part of the fourth linkage, near the front side, is sleeved on the outside of the limiting shaft and rotatably connected to the limiting shaft.

[0015] The limiting shaft is used to restrict the forward and backward movement of the fourth link, so that the fourth link can only swing about the axis of rotation of the limiting shaft.

[0016] Furthermore, the front side of the scraper is hinged with a third linkage assembly for controlling its forward and backward movement. The third linkage assembly includes a third roller, a seventh link, and an eighth link. The third roller is positioned above the third cam and is fixedly connected to one end of the seventh link. The other end of the seventh link is rotatably connected to the limiting shaft. An inclined eighth link is fixedly positioned above the end of the seventh link near the limiting shaft, and the top of the eighth link is rotatably connected to the connecting shaft.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by using the cam drive assembly composed of the second cam and the second linkage assembly, the up and down movement of the scraper can be controlled; by using the cam drive assembly composed of the third cam and the third linkage assembly, the forward and backward movement of the scraper can be controlled; and since the two cams are driven by the same drive shaft, the scraper can achieve compound movement in the forward and backward and up and down directions during the operation of the device. Through the forward and backward movement and the lifting and lowering action of the scraper, it is ensured that the eggplant wrapper remains flat at all times when it is wrapped around the eggplant embryo, thus playing the role of spreading the eggplant wrapper.

[0018] Furthermore, the trimming mechanism includes a trimmer, which is located on the right rear side of the rotating roller. An L-shaped connecting rod is provided below the rotating roller, and the bottom end of the L-shaped connecting rod is fixedly connected to the rear end of the bracket. A fourth roller is provided at the front end of the bracket, and the fourth roller is located above the front side of the fourth cam. The middle part of the bracket is hinged to the mounting base, and the mounting base is fixedly installed on the inner side of the right support plate and located above the camshaft.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the trimming mechanism can assist in completing the final trimming action of the wrapper application process. This action is not necessary. For medium and large cigars, the end of the cigarette is more aesthetically pleasing after using the trimming tool, but it has little effect on small and mini cigars.

[0020] Furthermore, the needle-picking mechanism includes a cylinder, which is fixedly mounted on a mounting plate on the outer side of the top of the left support plate. A needle is fixedly connected to the telescopic end of the cylinder. The needle is located on the right side of the eggplant embryo and is parallel to the eggplant embryo, and is used to pick off the eggplant skin during the conveying process. A three-position four-way solenoid valve for controlling the operation of the cylinder is also connected upstream of the cylinder.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: through the set needle picking mechanism, the needle extends outward with the operation of the cylinder, which can pick off the conveyed eggplant wrapper and put it onto the eggplant embryo, thus completing the start action of the eggplant wrapper application process.

[0022] Furthermore, the gearboxes on the two rotating shafts are symmetrically arranged, and the positions of the rotating rollers and the linkage shafts on the two gearboxes are symmetrical to each other.

[0023] Furthermore, each end of the limiting shaft is provided with a mounting ear, and the mounting ear is provided with a mounting hole. The mounting ear is fixedly connected to the left support plate and the right support plate through a fixing bolt provided in the mounting hole.

[0024] Furthermore, there is a gap between the two pinions, and they are in a non-meshing state.

[0025] Compared with existing technologies, the beneficial effects of the cigar wrapper applicator provided by this invention are as follows: By setting a camshaft, a first motor drives the camshaft to rotate, simultaneously driving four cams to rotate, thereby controlling the operation of the rolling roller opening and closing mechanism. The two pairs of rotating rollers on both sides provide power for the rotation of the cigar blank during the wrapper application process, thereby causing the upper rotating roller to rub and rotate the cigar blank, realizing the wrapper application operation; and combined with the wrapper spreading mechanism, under the drive of the second and third cams, the second and third linkage assemblies work together to realize the forward, backward, and upward movement of the scraper. This device can flatten the wrapper of cigars before rolling, effectively preventing quality problems caused by wrinkles when the wrapper is rolled onto the cigar blank, thus improving the quality of wrapper application. Through a trimming mechanism driven by a fourth cam, the trimmer can move forward and backward, trimming medium and large cigars to make the ends of the cigarettes more aesthetically pleasing, further improving product quality. This cigar wrapper application device features a compact structure and stable and efficient operation of all components, automating the wrapper application process and significantly improving cigar production efficiency and quality.

[0041] As shown in Figures 1-3, this invention provides a device for applying a wrapper to a cigar blank, comprising a support 1, a camshaft 2, and a limiting shaft 3. The support 1 includes a connecting plate 11 for mounting on a workbench, with a left support plate 12 and a right support plate 13 parallel to each other at both ends of the connecting plate 11. The camshaft 2 and the limiting shaft 3 are both mounted between the left support plate 12 and the right support plate 13 and are parallel to each other. The camshaft 2 is rotatably connected to the left support plate 12 and the right support plate 13, and the limiting shaft 3 is fixedly connected to the left support plate 12 and the right support plate 13. A first motor 4 for driving the camshaft 2 to rotate is provided at one end of the camshaft 2. The top of the left support plate 12 is equipped with a needle-picking mechanism for picking off the eggplant wrapper and a rolling roller rotation mechanism for rotating the eggplant embryo 100. From left to right, the camshaft 2 is equipped with a first cam 21, a second cam 22, a third cam 23 and a fourth cam 24 that are parallel to each other. The first cam 21 cooperates with the rolling roller opening and closing mechanism to roll the outer wrapper of the eggplant embryo 100. The second cam 22 and the third cam 23 both cooperate with the wrapper spreading mechanism to achieve wrinkle prevention and flattening of the wrapper. The fourth cam 24 cooperates with the trimming mechanism to complete the finishing action after the wrapper is applied to the eggplant embryo 100.

[0042] In use, the eggplant embryo 100 is mounted on the eggplant embryo support 66 and the support plate 131. When the eggplant wrapper is conveyed to the picking needle mechanism, the picking needle mechanism picks the eggplant wrapper onto the eggplant embryo 100. At the same time, the camshaft 2 drives the first cam 21 to rotate, which works in conjunction with the first connecting rod assembly 7 to close the winding roller opening and closing mechanism. The winding roller rotation mechanism drives the eggplant embryo 100 to rotate. During the rotation of the eggplant embryo 100, the eggplant wrapper is gradually wound onto the eggplant embryo 100. Meanwhile, during the eggplant wrapping process, the second cam 22 and the third cam 23 drive the second connecting rod assembly 81 and the third connecting rod assembly 82 to operate, controlling the lifting and lowering and forward and backward movement of the scraper 8, so that the scraper 8 can achieve the function of stretching the eggplant wrapper. Finally, after the eggplant wrapper is applied, the fourth cam 24 drives the trimmer 9 to operate and perform the trimming operation.

[0043] Furthermore, in the above technical solution, mounting ears 31 are provided at both ends of the limiting shaft 3, and mounting holes are provided on the mounting ears 31. The mounting ears 31 are fixedly connected to the left support plate 12 and the right support plate 13 through fixing bolts provided in the mounting holes.

[0044] In use, the limiting shaft 3 is fixedly installed between the left support plate 12 and the right support plate 13, and the limiting shaft 3 is rotatably connected to the fourth connecting rod 812 and the seventh connecting rod 822 respectively.

[0045] Furthermore, in the above technical solution, the needle-picking mechanism includes a cylinder 5, which is fixedly installed on the mounting plate 121 on the outer side of the top of the left support plate 12. The telescopic end of the cylinder 5 is fixedly connected to a needle 51, which is located on the right side of the eggplant embryo 100 and parallel to the eggplant embryo 100, and is used to pick off the eggplant skin during the conveying process. A three-position four-way solenoid valve for controlling the operation of the cylinder 5 is also connected upstream of the cylinder 5.

[0046] In use, cylinder 5 provides power to the picker needle 51. The three-position four-way solenoid valve connected upstream of the picker needle 51 is energized when the wrapper is conveyed to the wrapper device on the tobacco blank and approaches the position of the picker needle 51 of the picker needle mechanism. Cylinder 5 drives the picker needle 51 to move forward and pick off the wrapper. When the wrapper moves away from the wrapper device on the tobacco blank, solenoid valve Y2 is energized and cylinder 5 drives the picker needle 51 to move backward to reset. When the picker needle 51 picks the wrapper onto the tobacco blank 100, as the tobacco blank 100 rotates, the wrapper is gradually wrapped onto the tobacco blank 100 to achieve the wrapper effect.

[0047] In the above technical solution, the rolling roller rotation mechanism includes a second motor 6, which is installed on the outside of the left support plate 12 on the left side. A large gear 61 is coaxially mounted on the output shaft of the second motor 6. Two small gears 62, which are symmetrically connected above the large gear 61, are meshed. The rotating shafts 63 of the two small gears 62 pass through the left support plate 12 and the right support plate 13 and are rotatably connected to them. An eggplant support 66 is sleeved in the middle of the rotating shaft 63. A support plate 131 is provided on the top of the right support plate 13. The eggplant 100 is mounted on the eggplant support. On the frame 66 and support plate 131, a gear box 64 is provided at one end of the rotating shaft 63 near the inner side of the left support plate 12. Two rotating rollers 65 that can rotate with the gear box 64 are provided on the gear box 64 above the rotating shaft 63. The rotating rollers 65 are used to drive the eggplant 100 to rotate when closed. A linkage shaft 67 is also fixedly installed on the bottom right side of the gear box 64. A positioning plate 68 is sleeved on one end of the linkage shaft 67 and the rotating rollers 65 near the right side. The positioning plate 68 is used to limit the relative position between the linkage shaft 67 and the rotating rollers 65.

[0048] In use, the purpose of the rolling roller rotation mechanism is to enable the eggplant blank 100 to rotate by the rotating roller 65 when the rolling roller is closed; the first motor 4 is connected to the large gear 61, the large gear 61 meshes with two small gears 62 respectively, and the small gears 62 drive the rotating roller 65 to rotate through the gear box 64.

[0049] Furthermore, in the above technical solution, the gear boxes 64 on the two rotating shafts 63 are symmetrically arranged, and the positions of the rotating rollers 65 and the linkage shafts 67 on the two gear boxes 64 are symmetrical to each other.

[0050] In use, with the winding roller opening and closing mechanism open, the two gear boxes 64 are positioned with their bottom ends close to each other and their top ends far apart, forming a triangular area between them. The needle picking mechanism and the eggplant embryo 100 are located within this triangular area. When the winding roller opening and closing mechanism is closed, both gear boxes 64 rotate around the rotating shaft 63, and their top ends approach each other, thereby shrinking the triangular area between them and achieving a closing effect. After closing, the rotating roller 65 above the two gear boxes 64 can contact the eggplant embryo 100, and under the action of the rotating roller 65, it drives the eggplant embryo 100 to rotate.

[0051] Furthermore, in the above technical solution, there is a gap between the two pinions 62, and they are in a non-meshing state.

[0052] As shown in Figure 4, further in the above technical solution, the winding roller opening and closing mechanism includes a first linkage assembly 7. The first linkage assembly 7 includes a first roller 71, a first connecting rod 72, a second connecting rod 73, two third connecting rods 74, and a pin 75. The first roller 71 is disposed on the front side of the first cam 21 and is fixedly connected to the bottom end of the first connecting rod 72. The top end of the first connecting rod 72 is fixedly connected to the bottom end of the second connecting rod 73 and there is an angle between them. The top end of the first connecting rod 72 is hinged to the bottom end of the two third connecting rods 74 through the pin 75. The two third connecting rods 74 are symmetrically arranged, and the top ends of the two third connecting rods 74 are respectively sleeved on the linkage shaft 67 and rotatably connected to the linkage shaft 67. An arc-shaped surface is provided at the connection between the first connecting rod 72 and the second connecting rod 73, and the limiting shaft 3 is slidably connected to the arc-shaped surface.

[0053] It should be noted that when the rolling roller opening and closing mechanism is open, it is used to complete two actions: feeding the eggplant blank 100 into the wrapper and removing the wrapped cigarette. When the rolling roller opening and closing mechanism is closed, the eggplant blank 100 completes the wrapping action within the closed rolling roller opening and closing mechanism.

[0054] In use, the second motor 6 provides power to the entire camshaft 2, which drives the first cam 21 to rotate. When the high point of the first cam 21 contacts the first roller 71, the pin 75 is pulled down through the movement of connecting rod 1 72 and connecting rod 2 73. When the pin 75 is pulled down, the included angle of the two connecting rods 3 74 decreases, and the entire winding roller opening and closing mechanism closes. When the contact position between the first cam 21 and the first roller 71 misses the high point, the pin 75 rises, the included angle of the two connecting rods 3 74 increases, and the entire winding roller opening and closing mechanism opens.

[0055] As shown in Figures 5-6, further in the above technical solution, the peeling mechanism includes a scraper plate 8, which is disposed above the front side of the rotating roller 65. A second linkage assembly 81 for controlling its lifting and lowering is fixedly connected to the front side of the scraper plate 8. The second linkage assembly 81 includes a second roller 811, a fourth linkage 812, a fifth linkage 813, and a sixth linkage 814. The second roller 811 is disposed above the second cam 22 and is fixedly connected to one end of the fourth linkage 812. The other end of the fourth linkage 812 is hinged to the bottom end of the fifth linkage 813. The top end of the fifth linkage 813 is fixedly connected to the bottom end of the sixth linkage 814. The top end of the sixth linkage 814 is fixedly connected to the connecting shaft 80 disposed on the front side of the scraper plate 8. The middle part of the fourth linkage 812 is sleeved on the outside of the limiting shaft 3 near the front side and is rotatably connected to the limiting shaft 3.

[0056] In use, the lifting and lowering of the scraper 8 is controlled by the second cam 22. The second motor 6 provides power for the rotation of the camshaft 2. The camshaft 2 drives the second cam 22 to rotate. When the high point of the second cam 22 contacts the second roller 811, the end of the connecting rod 4 812 in the second connecting rod assembly 81 connected to the second roller 811 rises, while the other end falls, thereby pulling down the connecting rod 5 813 and the connecting rod 6 814, which in turn drives the scraper 8 to rise. Conversely, when the low point of the second cam 22 contacts the second roller 811, the end of the connecting rod 4 812 in the second connecting rod assembly 81 connected to the second roller 811 falls, while the other end rises, thereby pushing the connecting rod 5 813 and the connecting rod 6 814 upward, which in turn drives the scraper 8 to fall.

[0057] Furthermore, in the above technical solution, the front side of the scraper 8 is also hinged with a third linkage assembly 82 for controlling its forward and backward movement. The third linkage assembly 82 includes a third roller 821, a seventh linkage 822, and a eighth linkage 823. The third roller 821 is disposed above the third cam 23 and is fixedly connected to one end of the seventh linkage 822. The other end of the seventh linkage 822 is rotatably connected to the limiting shaft 3. An inclined eighth linkage 823 is fixedly disposed above the end of the seventh linkage 822 near the limiting shaft 3. The top of the eighth linkage 823 is rotatably connected to the connecting shaft 80.

[0058] In use, the forward and backward movement of the scraper 8 is controlled by the third cam 23. The second motor 6 provides power for the rotation of the camshaft 2. The second motor 6 drives the third cam 23 to rotate. When the high point of the third cam 23 contacts the third roller 821, the end of the connecting rod 7 822 in the third connecting rod assembly 82 connected to the third roller 821 is raised. Then the connecting rod 7 822 rotates around the axis of the limiting shaft 3, and drives the connecting rod 823 and the scraper 8 to move backward, away from the position of the rolling roller rotating mechanism. Conversely, when the low point of the third cam 23 contacts the third roller 821, the end of the connecting rod 7 822 in the third connecting rod assembly 82 connected to the third roller 821 is lowered. Then the connecting rod 7 822 rotates in the opposite direction around the axis of the limiting shaft 3, and drives the connecting rod 823 and the scraper 8 to move forward, closer to the position of the rolling roller rotating mechanism.

[0059] It should be noted that the forward and backward movement and the lifting and lowering of the scraper 8 are compound movements.

[0060] As shown in Figure 7, further in the above technical solution, the trimming mechanism includes a trimmer 9, which is located on the right rear side of the rotating roller 65. An L-shaped connecting rod is provided below the rotating roller 65, and the bottom end of the L-shaped connecting rod is fixedly connected to the rear end of the bracket 91. A fourth roller 92 is provided at the front end of the bracket 91, and the fourth roller 92 is located above the front side of the fourth cam 24. The middle part of the bracket 91 is hinged to the mounting seat 132, and the mounting seat 132 is fixedly installed on the inner side of the right support plate 13 and located above the camshaft 2.

[0061] In use, the second motor 6 drives the camshaft 2 to rotate. When the high point of the fourth cam 24 contacts the fourth roller 92, the fourth roller 92 rises, thereby causing the end of the bracket 91 connected to the fourth roller 92 to rise and the end connected to the L-shaped connecting rod to fall, thus causing the bracket 91 to rotate at a certain angle, thereby causing the trimmer 9 to move backward. Conversely, when the low point of the fourth cam 24 contacts the fourth roller 92, the end of the bracket 91 connected to the fourth roller 92 falls and the end connected to the L-shaped connecting rod rises, thereby causing the trimmer 9 to move forward and perform the trimming operation.

[0062] Specifically, the principle of this invention is as follows: the eggplant embryo 100 is mounted on the eggplant embryo support 66 and the support plate 131. When the eggplant wrapper is conveyed to the picking needle mechanism, the picking needle mechanism picks the eggplant wrapper onto the eggplant embryo 100. At the same time, the camshaft 2 drives the first cam 21 to rotate, which works in conjunction with the first connecting rod assembly 7 to close the winding roller opening and closing mechanism. The winding roller rotation mechanism drives the eggplant embryo 100 to rotate. During the rotation of the eggplant embryo 100, the eggplant wrapper is gradually wound onto the eggplant embryo 100. Meanwhile, during the eggplant wrapping process, the second cam 22 and the third cam 23 drive the second connecting rod assembly 81 and the third connecting rod assembly 82 to operate, controlling the lifting and lowering and forward and backward movement of the scraper plate 8, so that the scraper plate 8 can achieve the function of stretching the eggplant wrapper. Finally, after the eggplant wrapper is applied, the fourth cam 24 drives the trimmer 9 to operate and perform the trimming operation.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
